TRANSPARENT ARRANGEPAENT Fil edvsept. 9, 1951 y. fil/en ausen PatentedFeb. 26, 1935 UNITED STATES TRANSPARENT ARRANGEMENT Franz Ovenhausen,Steinheim, Germany Application September 9, 1931, Serial No. 561,972 I vIn Germany May 15, 1929 l 9 Claims. (01. 249-408) The present inventionrelates to a device for the purpose of screening off or attenuatinglight. This device is particularly adapted for being used as screen inconjunction with illuminating fittings. The screens are made to consistin accordance with the present invention of a spirally shaped woodenveneer leaf, in connection with which the veinage of the wood is made totake a radial course. An arrangement for the production of such veneershas been described in my American Patent 1,807,251. The presentinvention, however, is not to be limited to screens having been producedin accordance with this patent.

An essential feature of the present invention further consists therein,that the spirally shaped veneer is pared off by means of a tool of suchthickness and under such angle, that the screen or the transparentessentially exhibits a veinage fully repeating itself. To the spirallyshaped veneer a curved or profiled form is advantageously imparted bythe employment of curved cutters. Furthermore, the veneer may be coveredwith glass or with a similar material on either side.

In the drawing the invention has been shown by way of example,

Fig. 1 showing an arrangement in accordance with the invention in sideelevation,

Figs. 2 and 3 representing further examples of performance in accordancewith the present invention,

Fig. 4 being a sectional view of a further example of performance, inaccordance with the present invention.

In the drawing 11 indicates a spirally shaped veneer exhibiting aveinage essentially fully recurring. The parts a have substantially theshape of a truncated cone. In Fig. 1 the point of the cone has beenreplaced by the stud 0 being connected with the part a in a suitablemanner, e. g. by glueing or by means of a screw connection. The stud 0may be made to serve for the reception of a mount for an electric globe.In accordance with Fig. 1 the part a merely possesses one joint g. Ifnecessary, also several joints may be provided at the part a. Thisjoint, however, takes a wave-line course, preferably such a course,which yields a dove-tailed joint.

The example of performance in accordance with Fig. 2 shows an upper parta and a lower part b. The parts a and b are connected with each other ina suitable manner, In this example of performance the point of the partb has been replaced by a stud c. In contradistinction to the part a thepart b is made to consist of a hollow cut spirally shaped veneer.

Fig. 3 shows a spherical illuminating fitting. The sphere has beencomposed of separate veneer leaves d, showing each for themselves afully recurring veinage. ,f are ledges being provided to hold theseparate veneer leaves d together. The veneer leaves may also suitablybe employed as transparents for illuminated advertising sign-boards,transparent table-tops, illuminated floorings and the like.

Fig. 4 represents a sectional view of a tabletop equipped in accordancewith the invention. h indicates glass plates in between which 2, veneerleaf i has been placed. This veneer leaf corresponds in plan view to theintermediate veneer leaves at in accordance with Fig. 3. k is anelectric globe situated belowthe table-top. In conjunction with asuitable thickness of the glass plate this arrangement may also beemployed as flooring. Below the joint of the wooden veneer leaf a thinveneer or a strip of paper may suitably be placed and glued to thewooden veneer.

I claim:

1. In a casing a wall, the casing adapted for the reception of anilluminating fitting, the 'wall consisting of a veneer leaf with aveinage essentially taking a radial course, said leaf consisting of anintegral piece of wood.

2. In a casing in accordance with claim 1, said wooden veneer leaf beingdesigned as a hollow cone. s

3. In a casing a wall in accordance with claim 1, said wooden veneerleaf being designed as hol-,

low cone with curved generatrix.

4. In a casing in accordance with claim 1, on the outside of the woodenveneer leaf a transparent disk and fastening means interposed betweensaid disk and the wooden veneer leaf.

5. In a casing in accordance with claim 1, said wooden veneer leaf beingplaced between two transparent disks.

, 6. In a casing in accordance with claim 1, said wooden veneer leafbeing interposed between two transparent disks and packings between theedges of the disks.

7. In a casing in accordance with claim 1, said joint edges having theshape of a wave line.

8. In a casing in accordance with claim 1, said joint edges beingdesigned as serpentine line in such a manner, that the tenons thusformed are adapted to grip each other in dove-tail or swallow-tailfashion.

9. In a casing a wall, the casing adapted for the reception of anilluminating fitting, the wall being designed as hollow rotary body andcontaining veneer leaf with a veinage taking a course essentiallyparallel to generatrix of said body, the joint edges of said veneer leafbeing immediately connected with each other.
